Its a tire tube and its the size it is supposed to be. Good fit. Worked great.

These inner tubes are made of a thick quality rubber and they come with extra valve stems. They were easy to install on my garden wagon and they have so far held air with no issues. The tubes came with spare valve and a core removal tool, which was a nice surprise. This was a good option that was also a great price.

These fit my hand truck. Nice they came with a pack of 2. That way I could put new tubes in on both wheels.

Had two air compressor tires that had a slow leak, so I installed these tubes inside each tire which didnt take too long and held air with no leaks. This was a cheaper and easier alternative to keep the tires inflated vs buying two new rubber tires.

I bought these to replace the tubes on my UGV, and the sizing seems accurate and so far they are holding air well. They seem a tad thinner than the tubes that came in the tires I have, but so far they are holding air well and they seem to be decent quality. I will update if they start to leak or if they fail, but so far so good! Im quite happy with these. I dont buy tubes like this often, but at $12 for the pair at the time of this review theyre a good value.

Product arrived in a soft envelope as you see in the photos. The kit is complete for 2x inner tube replacements on a common hand truck sized tire, but make sure you read the outside of your tire to make sure it matches the item description. I like that the kit includes a valve stem removal tool and some spare screw-in valves, but its only been a few times in my life that ive had to replace a valve, so just put it somewhere youll find it again. Apart from that, taking the old tire off of the rim is the hardest most frustrating part of the process, and the need for special tools that you may or may not have, which is where the highest chances are youll accidentally put a hole in this new replacement inner tube. I was being as careful as I thought I could be and still managed to put a hole in one of the tubes, so im a bit disappointed that im now down 1 replacement tube because it didnt survive the process of putting the tire back over the rim. But that doesnt speak to the kit and inherent value it offers, which is good. Just make sure you tires are still soft and pliable before you do this job, otherwise you might want to consider other options (e.g. complete replacement non-inflatable tires or use of tire sealing compound)

These worked well as a tire tube for fixing wheels on a cart. Seemed a little thinner that others I have purchased, but will have to try them and see.

Great for revamping for spring! Works great!

The tubes in my gorilla cart stopped holding air. These were a pretty good replacement. The bent air stems are unnecessary but dont cause any problems. This was not a real easy job to do. In the future Ill probably buy a new set of tires and wheels from Harbor Freight rather than swapping tubes.

This is a very good and thick quality tire and I used to to replace the tire on my wheelbarrow. It works great so far and I expect it will last for a long time to come. I recommend this inner tube it’s working great.
